One of the most important chemical reactions for renewable energy technologies such as fuel cells and metal–air batteries today is oxygen reduction. Due to the relatively sluggish reaction kinetics, catalysts are necessary to generate high power output. The most common catalyst for this reaction is platinum, but its scarcity and derived high price have raised the search for abundant nonprecious metal catalysts. Inspired from enzymatic processes which are known to catalyze oxygen reduction reaction efficiently, employing transition metal complexes as their catalytic centers, many are working on the development of bioinspired and biomimetic catalysts of this class. This research news article gives a glimpse of the recent progress on the development of bioinspired molecular catalyst for oxygen reduction, highlighting the importance of the molecular structure of the catalysts, from advancements in porphyrins and phthalocyanines to the most recent work on corroles, and 3D networks such as metal–organic frameworks and polymeric networks, all with nonpyrolyzed, well‐defined molecular catalysts for oxygen reduction reaction.

生物启发的分子催化剂在燃料电池中进行氧还原反应的电催化

对于可再生能源技术（例如燃料电池和金属空气电池）而言，当今最重要的化学反应之一就是减少氧气。由于相对较慢的反应动力学，催化剂对于产生高功率输出是必需的。该反应最常见的催化剂是铂，但其稀缺性和衍生的高价促使人们寻求丰富的非贵金属催化剂。从已知的以过渡金属络合物作为催化中心的酶催化方法可以有效地催化氧还原反应开始，许多人正在研究开发此类生物启发和仿生催化剂。这篇研究性新闻文章简要介绍了生物启发的用于还原氧的分子催化剂的最新进展，
